How can you increase the sensitivity of a liquid in a glass thermometer?
The sensitivity of a mercury thermometer can be increased by using a smaller mercury bulb, thinner wall and smaller bore. A smaller bulb contains less mercury and hence absorbs heat in shorter time. As a result it can response faster to temperature change.
How can you increase the sensitivity of thermometer explain?
The sensitivity of a thermometer can be increased by using a substance having a high coefficient of expansion and uniform expansion so that it expands with the slightest change in temperature.
What affects the sensitivity of a liquid in glass thermometer?
As sensitivity generally refers to the change in physical quantity (i.e. length of liquid column) per unit change in temperature, a greater bulb increases the sensitivity of a liquid in a glass thermometer.
How can the sensitivity of a mercury in glass thermometer be increased?
On the other hand more volume in the bulb means more liquid in the bulb to expand which means a given temperature change will result in more fluid being squeezed down the tube to travel farther which helps increase sensitivity in face of a larger bore.
Does larger bulb increase sensitivity?
How do you increase the sensitivity of a thermometer Igcse?
Some of the factors which increase sensitivity are:
- Using a thermometer with a smaller glass bulb, as a smaller bulb contains less liquid and therefore, absorbs heat in a shorter time.
- Using a narrow tube, as a small change in volume results in the liquid moving a larger distance along the tube.
What affects the sensitivity of a thermometer?
The Sensitivity of Liquid Thermometers Using a narrow tube, as a small change in volume results in the liquid moving a larger distance along the tube. Using a glass bulb with a thinner wall, as heat can be transferred to the bulb more easily and a small change in temperature can be more easily detected.
What does the sensitivity of liquid thermometers depend on?
The sensitivity of a thermometer is defined as the increase in the length of the mercury column per unit increase in temperature. The range of a thermometer, on the other hand, refers to the dissimilarity between the maximum and the minimum temperature. It is calculated in meter/degree Celsius.
Which thermometer is more sensitive?
gas thermometers
As a result, the increase in the volume of a gas will also be more than that of a liquid. Thus gases expand more than liquids, i.e., gas will expand more than liquids for the same tiny change in temperature. Hence, gas thermometers are more sensitive than liquid thermometers.
What causes the liquid in a thermometer to rise?
The liquid in the thermometer goes up when the thermometer is heated because heating makes the alcohol molecules of the liquid move faster. The extra speed of the molecules competes with their attraction for one another and causes them to move slightly further apart.
